UN Hazard Class: 4.2; UN Subsidiary Risks: 8
Chemical Dangers · 1건

Heating may cause violent combustion or explosion. Reacts violently with water. This produces flammable methanol and corrosive potassium hydroxide. The substance may ignite spontaneously on contact with moist air. The substance is a strong reducing agent. It reacts violently with oxidants. The substance is a strong base. It reacts violently with acid and is corrosive. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).

Packaging and LabellingAirtight. Unbreakable packaging. Put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.
Hazard Classes and Categories · 3건
